Todd, Zee has a couple of DDEC 11 and 111 from fire trucks but they take a lot of parts changing to work in a Prevost he was asking 5000 ea but the truck engines will cost him about 3 grand to convert to the Prevost setup

I don't know of any DDEC 11 bus engines (I guess that is what he has) for sale right now what's wrong with his is it not repairable ?

Seems if your replacing a like engine, most needed material should be available from the old engine, however with DDC, there is no end to the possibilities of what could & should be different, My education started by changing the transmission in the MC7 from the origional 4 speed to a RTO910 Road Ranger, flywheel, bell housing and engine mounts just for a start, DDC / Greyhound used a SAE 1 Bell Housing with a SAE 2 flywheel, that means the starter had to be moved closer to the crankshaft, so a different SAE 1 Bell Housing was required, one for the SAE 1 Flywheel, can get very interesting. Easy if you have a yard full of junk DDC engines.Good luckDave M

Runs good, smokes some on start up and at idle but once it gets out on the road clears up quickly.

Last few trips it made were from Nashville to Panama City Beach/Ft. Walton Beach, FL set the cruise on 73 mph and cruised all day no problems.

We retired the bus from service as it needed too much $ in body work and interior upgrades to make it "feasible" to keep in regular service. Seats have already been removed and is being used as a storage locker right now! (we can unload it fast if sold!)
